I am a huge Sig Sauer fan so I have kind of high expectations with a replica gun! The KJWorks lineup as a whole is really fantastic, and what I say about the KJWorks KP01-E2 (Sig Sauer P226) CO2 Blowback Airsoft Pistol can be said about the entire lineup. KJWorks makes a super well built product that replicates the real steal version almost exactly other then they shoot Airsoft BB's instead of actual bullets. When holding a KJWorks gun in the hand you can feel the quality, in weight, ballence and especially when operating the slide, trigger and other working parts. Everything just feels so perfect and responsive. For the money you can not go wrong with the KJWorks KP01-E2 (Sig Sauer P226) CO2 Blowback Airsoft Pistol or any other KJWorks gun for that matter.
